  • The importance of wastewater force main management

    Condition assessment and management of wastewater force mains has historically been challenging for operators. Conventional methods (e.g. visual inspection, sonar and laser profiling) do not provide a comprehensive condition assessment because they do not quantify the loss of structural capacity. As WEFTEC 2013 in Chicago approaches, ...

  • Flavour Industry Wastewater Management Case Study

    This study is carried out to propose an appropriate treatment technology for wastewater discharged from a flavor production factory. Industrial wastewater discharged from this factory ranges between 50–70 m3/d with an average value of 60 m3/d. The major source of pollution in this factory is due to cleaning of the vessels therefore the treatment has been carried out on the end-of pipe wastewater. ...

  • Improved Wastewater Management for Electroplating: Premier Plating Company

     A custom-designed waste water management system is saving Premier Plating Company $14,400 a year on the cost of treatment and disposal of waste produced by the electroplating process. The company has also reduced water consumption at its plants by a massive 2.2 million litres per year. The system cost only $15,000, so the company’s investment has been paid back in less than a year. The ...


  • Decentralized wastewater management in Kieu Ky Vietnam

    1. Overview and Key Points In order to eliminate the common ‘out of sight out of mind approach’ in sanitation, whereby sewers and/or drains are discharged into rivers, a Decentralized Wastewater Treatment System (DEWATS) was designed and implemented in Kieu Ky to treat wastewaters arising residential properties and various craft industries. A clear understanding of topography, ...
